Sound output device keeps changing when using headphones
Recently upgraded to 12.10. Having issues with sound when using headphones plugged into the front ports. Something that doesn't happen when booting to windows - so fairly confident it's an Ubuntu issue.
When listening to any sound, music, video etc the sound levels jump up and down and click. If I open "sound" from the settings menu when playing videos or music and viewing the "output" tab I can see "headphone - built-in audio disappear and reappear (very quickly) so I'm guessing the system is jumping back to the "analogue output" and back again which is why the sound volume changes and clicks.
Worth noting I never used my headphones when 12.04 was installed so not sure if it's this OS or Ubuntu hates my hardware generally. Booted from live cd (usb) to 12.04 and there wasnt any issue.
Anyone seen this before? any advice?
Sound is built in to motherboard. I have the Gigabyte GA-X58A-UD5.
